What You Should Know

• What is active learning:
  • Batch Active Learning
  • Selective Sampling and Active Learning
• Active learning could provide exponential improvements in label complexity (both theoretically and practically)!
• Common heuristics (e.g., those based on uncertainty sampling).
• Sampling bias.
• Safe Disagreement Based Active Learning Schemes.
  • Understand how they operate precisely in the realizable case (noise free scenarios).
